When a job is stuck in a status, you can use System_ForceJobStatusUnknown to set the job to unknown.
Please be aware that setting to unknown will not stop whatever the job is doing, but will simply change the Status to Unknown. RMJ will no longer try to monitor the process started for the Job.
However as the Process remains running in the background, at a later point in time the Process may update the Job and change the Status to for example Completed/Error.
Here is how to submit the System_ForceJobStatusUnknown:
Go to definitions>Processess and search on the search bar for System_ForceJobStatusUnknown. Once found, Right-click on System_ForceJobStatusUnknown>submit> you will get this window popup:
Fill out the ID field with the Job ID and Submit.
Should you have multiple Jobs, you can use the List of IDs (comma-separated values) to perform this task for multiple Jobs reducing the number of manual actions.
